* Ink yield calculation is based on printing Canon 24 standard digital images on Photo Paper Plus Glossy (6" x 4" borderless print) with default settings in Windows XP driver. The figure above is an average value, measured when printing continuously using the ink immediately after it is unsealed, until the ink is out. Ink yield may vary depending on photos printed, applications software used, print mode and type of paper used. This should be used as a guide only and does not take into account ink that might be used for head cleaning or head refreshing to maintain printer performance.
